Description
Technical field
The present invention relates to LTE system power control technology field, particularly relate to a kind of ascending power control method and system.
Background technology
LTE (Long Term Evolution, Long Term Evolution) power in system is controlled according to the direction of link and is divided into two kinds of downlink power control and uplink power control, wherein, downlink power control is in frequency with on the time, to adopt constant transmitting power, be that downlink power control is with each RE (Resource Element, resource particle) be the power distribution strategies of unit, and the object of uplink power control is mainly to make (the Modulation And Coding Scheme for identical MCS, modulation and coding strategy), different user arrives PSD (the PowerSpectral Density of base station, power spectral density), that is the power on unit bandwidth about equally.
LTE system adopt with OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexi) in the cell mobile communication systems building for access mode, can accomplish that frequency duplex factor as one is 1, be that all communities in whole system coverage are used the user of identical frequency band Wei Zhe community that service is provided, can greatly improve the availability of frequency spectrum like this, because LTE system frequency resource is limited, taking 3 or more 20MHz carrier frequency, to carry out inter-frequency networking be unpractical.And for the user of cell edge, the user who takies same carrier resource due to neighbor cell is larger to its interference ratio, in addition itself is far away apart from base station, its SINR (Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio) relatively just less, although cause the situation that the higher Cell Edge User service quality of the throughput of whole community is poor, throughput is lower.
In order to solve LTE system in the problem of cell edge serious interference, 3GPP (3rd Generation Partnership Project, third generation partner program) propose multiple solution, comprised interference randomization, interference delete and interference coordination technique.The statistical property that wherein interference randomization utilization is disturbed suppresses disturbing, and error is larger; Interference delete technology can significantly be improved the systematic function of cell edge, obtain higher spectrum efficiency, but for the less business of bandwidth (as VoIP (Voice over Internet Protocol, the networking telephone)) not too applicable, in OFDMA (Orthogonal Frequency Division Multiple Access, OFDM) system, realize also more complicated.
The core concept of the interference coordination technique of the system of LTE is proportion multiplex technique, makes the distance of the interference signal source between neighbor cell far away as far as possible, thereby suppresses the interference of neighbor cell, reaches and improves transmission quality, improves the effect of throughput.In addition, in order to make minizone, can better interconnect, 3GPP agreement has been stipulated can be by the foundation of X2 interface between base station, realize the mutual of cell information between base station, wherein the load deixis of X2 interface makes OI (the overload indicator of transmission system between base station, overload is indicated) and HII (high interference indicator, high interference indication), thereby realize the interference coordination of minizone.
Yet, the conventional means that at present interference coordination is carried out in indication based on OI are that receive after the interference indication of adjacent area base station, only to using the user of the Resource Block subset being disturbed to implement power control strategy, but so easy generation mistuning, or according to disturbed user's position Modulating Power to untapped primary/secondary carrier resource piece, but which need to confirm whether disturbed user and this user are strong interferers; Or be that receive while disturbing overload indication base station, according to disturbing overload indication, adjust Po_UE_PUSCH (j) (the specific fiducial value of terminal) of center of housing estate and/or Cell Edge User etc., these methods all require to determine interference source user, then by scheduling, reconfigure the methods such as initial expectation received power and realize interference coordination, in implementation procedure, easily there is interference source user erroneous judgement that the not confirmability due to user's scheduling resource block causes and the Initial Trans problems such as slow and DeGrain of regulating the speed.
Summary of the invention
Based on this, be necessary to cause slowly the problems such as DeGrain for easily occurring in existing disturbance coordination method implementation procedure in background technology that interference source user erroneous judgement and Initial Trans are regulated the speed, a kind of ascending power control method is proposed, by controlling the ascending power of Cell Edge User end, realize minimizing presence of intercell interference, and implementation procedure complexity is little, simple to operate.
